I think it's great for it to be used by end users as a system library /
utility. i.e. like you would a the system libc -- so if you can write a
little python script that only uses the stdlib -- you can simply deliver
that script.

But if you want to go an install a bunch of extra non-standard packages
(or, for heaven's sake, want a version with bug fixes!), they you really
are better off installing a new python you can control.

The system
> Python should be left alone as it is.


By the way, py2app will build an application bundle that depends on the
system python, indeed, that's all it will do if you run it with the system
python, as Apple has added some non-redistributable bits in there. But
things get kin dof confusing if you want to rely on non-system packages...
